Machine Number Switch
Note * For the CS1W-CT021/041 40 CIO-words and 400 DM-words are allocated.
Counter Type Switch
Note * Circular and Linear Counter are fully DM-configurable. Refer to Operation Manual (Cat. No. W902-E2-1).
Name Function
MACHINE No. Sets the Machine Number* (00 - 92).
•Machine Numbers 93-99 cannot be set and will generate an error.
•Make sure each Machine Number is used only once per CS1-CPU.
Be sure to turn off the power to the Unit before setting the Machine Number.
